Policies

The Python SDK intentionally exposes policy streams only. Unary policy list/get/create/update/ delete methods require JWT/session administration and are not part of this API-key SDK.

Async method	Sync method	Event type
`subscribe_subaccount_policies`	`subscribe_sync`	`SubaccountPolicy`
`subscribe_api_policies`	`subscribe_api_policies_sync`	`ApiPolicy`

api_policies = await client.policies.subscribe_api_policies(
    account_id=client.default_account_id,
)
async with api_policies:
    async for policy in api_policies:
        print(policy.id, policy.revision)
        break

Both are private channels and require API-key credentials, Account ID, and the corresponding policy read permission. Subscription return means the private token and Centrifugo handshake succeeded.

Policy events may include MFA requirement flags. They describe venue policy; this SDK cannot perform an MFA challenge. Manage assignments and mutations in the Polyester app/TypeScript session client.
